Jewelry Store - Ventilation Requierments

[MechGuy22]

Im working on a Jewelry store. Obviously the store part is pretty simple. Im just concerned about the backroom. The Jeweler stores a couple large tanks of oxygen that he uses for making jewelry, and also has a tank of acetylene. Im sure he uses these chemicals to weld, which means they are burning, which means we need ventilation. Does anyone have an idea of a suggested air changes/ hour of ventilation?

Thanks!

what kind of juelery are they making?

Instead of space air changes, you should consider point of use ventilation, like they do for soldering.

I really think they are just doing alterations and repairs here. Not really making jewelry. The existing shop has nothing in it. This new store is only 2000 ft^2 so I dont think industrial ventilation will be a very good fit.

I think I am just going to do a downdraft vent and a overhead exhaust fan to keep the room negative. Maybe I was over-thinking this?

You should read the ACGIH before you conclude that it won't be useful. Any kind of ventilation, both industrial and other, is dealt with in the manual.

I will definitely see if I can find a copy. Thank You
